The tests use exactly the same questions and answers as the FCC written theory tests. If you can correctly answer them you can be sure of gaining your ham radio license. An added bonus is that every single question has some background information so that you can understand the reasoning behind each correct answer. Nu-Ware have tried to include everything you need to gain your ham radio license at any level, all in one package.
